Pokeatery, a customized poke concept with restaurants in San Mateo and Castro Valley, has opened its newest location — in downtown Walnut Creek.

It’s the first of three Northern California franchises that Gary Zhu and Julie Ren will operate for founders Joann and Derek Chung, who brought 20 years of sushi restaurant experience to the enterprise. The other city locations haven’t been finalized yet.

The new store is located at 1345 Newell Ave. near Broadway Plaza.

Pokeatery gives diners the option of building their own poke boxes around not just the typical ahi, salmon or albacore, but also hamachi or octopus. The kelp noodles are made in-house. Other offerings include pokeado toast, a poke play on avocado toast.
